lMPPtOVEMENT'lN HYDRATS Specification forming part of Letters Patent No. I00,255, dated March 1, 1870; antedated February 16, 18,70.

To all whom it may concern:

Beit known that we, S. G. OABELL, of Quincy, in the county of Adams and Sta-te of Illinois, and A. Q. ROSS, of Cincinnati, in the countyr of Haxniltonand State of Ohio, have invented certain new and useful Improvements inHydrants; and we do hereby declare that theV following is a full, clear, and exact description thereof', reference beiughad to' the accompanying drawings, making part of this. specification, and to the letters` ot' reterencemarked thereu1-like letters indicating like parts, wherever they occur.

'.lo enable others skilled in the art to construct and use our invention, we will proceed to describe it.

Our invention relates to hydrants; and it consists in the novelconstruction and arrangement ot' mechanical devices for allowing the water to liow from the stand-pipe int"=a`cy lindrical chamber, in order to avoid all liability to any injury'that inight, arise from the freezing of'the water therein in cold weather.

In the drawings, Figure 1 is a longitudinal vertical section. Fig. 2 is a top plan view l.of

lthe valve-seat detached.

We are aware that in hydrants as heretotore constructed there is frequently provision made for the escape of the water from the stand-pipe. consists in allowing the water to ilow into thev Surrounding earth, which in a. short time bei comes wet and works into and destroys thev valves, or llls up the waste-pipe and prevents the escape ot' the water.

The object of our invention is' to provide the hydrant with certain mechanical devices t'or allowing the water to tlow from the standpipe into a chamber, from which it is drawn again when the hydrant is operated, and in this way avoidletting it lrun out into the surrounding earth.'

ln constructing our hydrant we make a cylindrical reservoir or chamber, A, ofl any size desired and out of any suitable material, but preferably out ot' cast metal, and as clearly shown in Fi 1. Its lower end we construct with a short neck, k, provided with a screwthreadand to it connect a cap, B, having a suitable`screwthread for that purpose, and also having at its lower end al neck, a, properly made, to connect it with the watermain,

This provision, generally,'siniply as clearly shown in the same figure. Into the upper end of the '.neck k we screw a valveseat, C, having a perforated concave cap, D, screwed onto its lower end, and a bar, n, across Vitsupper end, with a small hole through it, and an intervening space on each side of it, as. clearly shown in Figs. 1 and 2. Inside ot' this valveseat. we place a check-valve, o, attached toastem, l, which passes through and moves easily; in the'cross-bar n and the lower 'end of the cap D, as clearly shown inv Fig. 1. About the -stern l we` place a spiral spring, d, with its lower end resting upon the upper side of the cap D, and its upper end against the under side of the check-valve c, and against the ,upper inner side ot the valve-seat we place an elastic packingring, e, for the check-valve to bear against, as shown in the same ligure.

In the cylindrical res voir'A weplace a closely-fittingpiston-heaefE, and connectv it byv a screw-thread or in any other suitablewayto a stand-pipe, F, (or, instead of a pipe, a solid shaft, as hereinafter described) the lower end ot which cornes liush with the inner face' of the head l, and has .securedv to' it a cross-bar, b, arranged so as to strike in its Adescent against the upper end of thevalve# stem yl. v .It is obvious that it' desired a solid shaft may be substituted for the stand-pipe F; but

in that oase it will be necessary to make-an opening, G, in the head E and provide it with a short neck, and attach thereto a rubber stand-pipe,-M, so arranged that its elasticity' may aid in elevating the piston-head.

In operating our hydrant device thus constructed, we place the reservoir A at any place desired in the ground or elsewhere in a locality sufficiently protected from-frost, con: neot itwith the water-main, and protect it on all sides with a suitable casing or covering, and provide the upper end ot' the stand-pipe F with a delivery-spout, and also with any suitabledevicefor moving it vertically. When we desire to draw water l'roin the\vaterinain,we depress the stand-pi pe, which, strikingagaiust the valve-stem l, forces down the check-valve @and allows the water to tlow up through the valve-scat andvon through the stand-'pipe Vhen all the water required. has been drawn, we raise the standpipe which allows the spring d to carry up the check-valve c against the elastic rubber ring e, and thus cui: oil the flow of Water from the main. At the saine time the head E is elevated and a chamber left beneath it, into which the Water from the stand-pi pe at once runs and leaves the pipe empty. In this Way the water is taken to a place i'ree from frost. W'hen it is `desired to draw water again, the stand pipe is forced down, and the water in the chamber is-then driven from it and carried out with the water, which iiows again from the main through the stand-pipe. It will thus beY readily seen that a hydrant with o ur devices thus constructed and arranged not only completely protects itselfagninst injury from frost, but also has no waste water discharginginto the surrounding` earth. to theinjiu'y oi the hydrant, as well as (o ils nastcfpipes.
